Final: Timelapse clips: Project Objective: The aim for this project is to make visible the amount of CO2 in the air. While we know CO2 is constantly around us, it is disturbing that we can’t see it. This air quality lamp table is an attempt to visualize this invisible data. An air quality sensor […]

Light + Energy Wk 11: CO2 Light
Updates: a.) Game Plan + BOM: https://docs.google.com/spreadsheets/u/1/d/1uW511rmpu_MMZTSMx1Qz7kdET3_OoLWMxrxNXt9VtNk/edit#gid=0 b.) Schematic Drawing: c.) Sketches + Cardboard Mockup d.) Playing with Materials e.) Air Quality Sensor: A lot to do on this front! There were hiccups with the sensor, but determined to get data logging for the air quality asap! CCS811 is here so I hooked […]
Light + Energy Wk 9 – 10: CO2 Light Concept
Project Objective: This is a 24 hour LED clock that will display the amount of CO2 every hour. Using an air quality sensor, I plan to track the amount of CO2 in the unit of parts per million (ppm) in my local surroundings (home and school) and visualize that data in the form of a […]
Energy Wk 6-7: Solar, Cool Bunny
Final Piece: Solar energy will power the wireless communication device and temperature/humidity sensor. When an unhealthy (for the bunny) combination of high temperature and high humidity is measured, the feather RF will communicate to the other feather RF to use the relay to turn on the fan. The fan will then be used to cool […]
Energy Wk 5: Solar
Assignment: Measure the power used when the platform running different operations. They will be the basis for an energy budget for your project. So, I ran into issues with using the 6V solar panel, I didn’t have screw terminals nor the right jack on hand. As an alternative, I decided to solder my own small […]
Energy Wk 4: Battery
Record the specs for 3 batteries: chemistry, voltage, and capacity (if capacity is in amp hours, can you get to watt hours?). Energy(wh) = voltage * current * time 1.) iPhone XS Battery : Chemistry: lithium ion Voltage: 3.8v Capacity: 2.658 Ah Watt hours: 3.8v * 2.658Ah = 10.1004 Wh 2.) Headphones Battery: Chemistry: Li-Polymer Voltage: […]
Energy Wk 4: Solar, Cool Bunny (wip)
Cool Bunny Project Objective: Solar energy will power the wireless communication device and temperature/humidity sensor. When an unhealthy (for the bunny) combination of high temperature and high humidity is measured, the feather RF will communicate to the other feather RF to use the relay to turn on the fan. The fan will then be used […]
Energy Wk 3: Kinetic Project
Sukanya, Sid and I worked came up with many ideas. Below are some of the sketches – it was not easy for us to decide. After many different ideas and exploration, we decided to make a kinetic hammer. We were inspired by Professor David Rios’ kinetic pedal synth. See here for reference video: https://vimeo.com/66357163 So […]
Energy Wk 2: Induction
Our kinetic energy group (Sukanya, Sid and I) tried out a few steps using the stepper motor. a.) We used the stepper motor, this is AC so we needed to add the diode rectifier to convert it to DC. We added a 470 µF capacitor, after the diode rectifier and before the LED in the […]
Energy Wk 1: Flash an LED with a Motor
Before realizing that we needed to power the led with either a magnet and coil or a dc motor, I looked into a couple of other different ways to power the led with kinetic energy. One of the more intriguing ideas I stumbled upon was the piezoelectric. I found this schematic online that I found […]
